Typesetting interactions diagram - with smartdiagram ? - (and bug/conflict between babel and smartdiagram)

Question

I am trying to typeset the following kind of diagram :

This is an interaction diagram I would use in functional requirements analysis (drawn with MS Word). I tried to use the smartdiagram package, this is a MWE of what I did :

\documentclass{article}

\usepackage[french]{babel}

\usepackage{smartdiagram}
\usesmartdiagramlibrary{additions}
\usetikzlibrary{babel}

\RenewDocumentCommand{\smartdiagramconnect}{m m}{%
    \begin{tikzpicture}[remember picture,overlay]
    \foreach \start/\end in {#2}
    \draw[additional item arrow type,#1]
    (\start) to (\end);
    \end{tikzpicture}
}

\begin{document}
    \smartdiagramset{/tikz/connection planet satellite/.append style={<->}}
    \smartdiagramadd[constellation diagram]{System,E1,E2,E3,E4,E5,E6}{}
    \smartdiagramconnect{->, bend right=15}{satellite3/satellite7}
\end{document}

Which gives :

To come closer to the original, here are a few points I would like to improve :

• Add text/label near arrows
• Change satellites shape to ellipse could be useful if text is larger (but I've seen there are workarounds to fit the text in modules)
• Individually change arrow types (->, <- or <->)

What I like in smartdiagram is that it cares of the formatting and it is easy to add nodes, even if some links need to be added by hand.

Is this achievable with this package (if so, any clue ?), or is plain tikZ a better way to go ?

By the way, if I activate babel package, \smartdiagramconnect does not work anymore.

EDIT: The babel issue is solved by adding \usetikzlibrary{babel}in the preamble.

Answer 1

The conflict can be resolved by loading \usetikzlibrary{babel}. You can modify the shapes of the satellites by loading \usetikzlibrary{shapes.geometric} and then just append the shape to the style. The individual arrows can also be done. I am just afraid to modify the nice smartdiagram layout too much, but anyway, here we go.

\documentclass{article}
\usepackage[french]{babel}
\usepackage{smartdiagram}
\usetikzlibrary{babel,quotes,shapes.geometric}
\usesmartdiagramlibrary{additions}

\RenewDocumentCommand{\smartdiagramconnect}{m m}{%
    \begin{tikzpicture}[remember picture,overlay]
    \foreach \start/\end in {#2}
    \draw
    (\start) edge[additional item arrow type,#1] (\end);
    \end{tikzpicture}
}

\NewDocumentCommand{\smartdiagramindividualconnect}{m}{%
    \begin{tikzpicture}[remember picture,overlay]
    \foreach \Y/\Z [count=\X starting from 2] in {#1}
    {
    \draw[additional item arrow type,\Y] (planet) to 
    node[midway,sloped,above]{\Z}
    (satellite\X) ;}
    \end{tikzpicture}

}

\tikzset{satellite/.append style={shape=ellipse}}
\begin{document}
    \smartdiagramset{/tikz/connection planet satellite/.append style={draw=none}}
    \smartdiagramadd[constellation diagram]{System,E1,E2,E3,E4,E5,E6}{}
    \smartdiagramconnect{->, bend right=15,"hello" near end,sloped}{satellite3/satellite7}
    \smartdiagramindividualconnect{{<->/A},{->/B},{>-/C}}
\end{document}

Just for fun an option usign basic tikz commands to obtain the example graph...

RESULT:
